"Freedom only for the supporters of the government, only for the members of one party — however numerous they may be — is no freedom at all. Freedom is always and exclusively freedom for the one who thinks differently. Not because of any fanatical concept of 'justice' but because all that is instructive, wholesome and purifying in political freedom depends on this essential characteristic, and its effectiveness vanishes when 'freedom' becomes a special privilege."
Prisoners Exercising (aka Prisoners' Round) by Vincent Van Gogh, 1890
